"I asked Dave to please send me his rules additions, for I thought a whole new system should be developed. A few weeks after his visit I received 18 or so handwritten pages of rules and notes pertaining to his campaign, and I immediately began work on a brand new manuscript. "Greyhawk" campaign started —the first D&D campaign! About three weeks later, I had some 100 typewritten pages, and we began serious play-testing in Lake Geneva, while copies were sent to the Twin Cities and to several other groups for comment. DUNGEONS & DRAGONS had been born."
